Carriers of THIS blood type are more likely to get Covid, says survey

New research suggests that blood type can influence a person's likelihood of developing Wovid-19.

Since the pandemic, scientists have struggled to understand why some people experience more severe symptoms than others.

Harvard study provides answers

Studies done at the beginning of the Covid-19 pandemic indicated that individuals withblood type A could be at a higher risk of infection when compared to type O carriers. Now, a recent survey published in the journal blood seems to confirm this theory.

According with the doctor. Sean Stowell, associate professor of pathology at Harvard Medical School and lead author of the study, People with blood type A are 20% to 30% more likely to be infected with the coronavirus compared to those with type O, for example.

Approximately one-third of the population in the United States has blood type A, while nearly half have type O. However, before continuing the article, it is important to emphasize that people of all blood types can contract the virus.

In fact, data collected by public health officials in the US reveal that most Americans have already been infected with the new coronavirus, even if it has not developed symptoms of the disease, which happens in the vast majority of chaos.

In addition to known factors such as the functioning of the immune system and the presence of pre-existing health, blood type seems to be one more element that influences the severity of illness.

According to the study conducted at Harvard, in a scenario where a person with blood type A and another with blood type O are exposed to an individual infected with covid-19, all other variables being equal, the person with blood type A is slightly more likely to get sick. This relationship was also observed during the SARS-CoV-1 pandemic in 2003.

future expectations

Although the World Health Organization (WHO) has declared the pandemic over, the virus is still circulating at levels similar to those of recent years, according to US wastewater data.

Currently, most cases are not serious, due to the fact that the majority of the population is, in one way or another, immunized against Covid-19.

More research is needed to determine whether Covid-19 also shows a preference for B and AB blood types. Furthermore, these studies may help to understand why other viruses, such as cholera and malaria, tend to have a preference for certain blood types.

The results obtained so far indicate the need for further studies in this area, providing valuable information to combat the disease and develop more effective prevention strategies.
